采用包含具有GaAs衬底的周期性波纹薄层的模型来研究波纹对纳米结构传输概率的影响。我们发现，传输带隙和共振隧穿畴出现的波纹，在隧穿畴的隧穿峰和谷的结果，相邻区域之间的边界，其中一个电子具有不同的有效质量，并可以通过层的厚度略有修改。这些结果为设计曲率可调滤波器提供了一种方法。
A model including a periodically corrugated thin layer with a GaAs substrate is employed to investigate the effects of the corrugations on the transmission probability of the nanostructure. We find that transmission gaps and resonant tunneling domains emerge from the corrugations, in the tunneling domains the tunneling peaks and valleys result from the boundaries between adjacent regions in which an electron has different effective masses, and can be slightly modified by the layer thickness. These results can provide a way to design a curvature-tunable filter.
